ount
Four independent AC output relays
come in a single standard panel-mount
package. Utilizing an AC switch output
with internal snubber, relays provide
greater protection against false trigger-
ing. Model choices include zero-volt-
age or random turn-on (phase control-
lable) switching.
Manufactured in Crydom's ISO 9001
Certified facility for optimum product
performance and reliability.
